State Dept. condemns arrests, repression in Russia

The White House has released a pre-taped farewell address from President Trump on his final full day in office.

"We did what we came here to do – and so much more," Trump said, speaking from scripted remarks directly into the camera and standing behind a lectern with the presidential seal. "This week, we inaugurate a new administration and pray for its success in keeping America safe and prosperous. We extend our best wishes, and we also want them to have luck -- a very important word."

Trump thanked several people, including Vice President Mike Pence.

"Most of all, I want to thank the American people," Trump said. "To serve as your president has been an honor beyond description. Thank you for this extraordinary privilege."

Trump then condemned the riot at the Capitol and called on Americans to "unite around our shared values."

"All Americans were horrified by the assault on our Capitol. Political violence is an attack on everything we cherish as Americans. It can never be tolerated," Trump said.

He warned that the greatest danger the country faces as he leaves office is "a loss of confidence in our national greatness" -- going on to talk about the shared "heritage" of the country under threat and condemning "political censorship and blacklisting."

"Now, as I prepare to hand power over to a new administration at noon on Wednesday, I want you to know that the movement we started is only just beginning," he said, closing out the 20-minute farewell address.

Vice President Mike Pence will not be attending Trump’s farewell ceremony at Joint Base Andrews on Wednesday, according to his schedule.

Instead, his only event of the day is to attend Biden's inauguration.

Biden and future first lady Jill Biden arrived at Joint Base Andrews shortly before 4 p.m. Tuesday.

They boarded their flight to Washington, D.C., from New Castle County Airport in Delaware and departed shortly after 3 p.m.

In Washington, the Bidens, as well as Vice President-elect Kamala Harris and her husband, Doug Emhoff, will take part in a national COVID-19 memorial service at the Lincoln Memorial Tuesday evening to honor the 400,000 Americans who have lost their lives to the virus.

Biden delivered short but emotional farewell remarks in a send-off event in Wilmington, Delaware, on Tuesday afternoon, and wiped away tears as he wished his adopted state -- which first elected him to U.S. Senate at the age of 29 -- goodbye.

Apologizing for his emotions, Biden said he'll always be "a proud son of the state of Delaware."

"Excuse the emotion, but when I die, Delaware will be written on my heart," Biden said, choking up.

Biden also recalled a story he often shared on the trail, noting the historic nature of his time as vice president, serving alongside the nation's first Black president and now being a part of another historic feat, being inaugurated with the country's first Black female vice president, saying, "That's America," to applause.

In another emotional moment, Biden said his only regret was that his late son, Beau Biden, wasn't there with them. The location Biden spoke at, the Joseph R. "Beau" Biden III National Guard/Reserve Center, was named for his son, who died of brain cancer in 2015.

"Ladies and gentlemen, I only have one regret, that he's not here, because we should be introducing him as president," Biden said.

Beau was 46 when he died, and Biden is hours away from being sworn in as the 46th president of the United States.

"I know these are dark times, but there's always light. That's what makes this state so special. That's what it taught me, it taught me the most -- there's always light," Biden told the small crowd of supporters.

Before he spoke, he gave a masked kiss on the cheek to his sister, Valerie Biden-Owens, who he has often described as his best friend, and during his remarks referenced all of the Biden family members who were in the crowd, including his son Hunter Biden, his wife Melissa, their young child, and Biden's grandchildren: Naomi, Finnegan, Maisy, Natalie and Hunter.
